本发明的实施方式Embodiments of the present invention

本申请提出一种饮水机的控制方法，饮水机具有N个超声波探头。The present application proposes a control method for a water dispenser, wherein the water dispenser has N ultrasonic probes.

在饮水机的自动出水停水的实现上，超声波的测量技术非常具有性价比。而超声波就是利用声波遇到障碍物具有反射的特点，超声波（换能器）探头发射声波，然后接收来自四面八方的漫反射，然后得到一条具有二维特征的曲线f（x，y）如图1。X轴为时间，对应声波所辐射区域各种高度的信息，Y轴为幅值，对应X轴高度的反射强度的信息。而在饮水机出水口整个超声波的辐射范围内，会有很多的高度及幅值的信息f1(x1，y1)，f2(x2，y2)……，fn(xn，yn)，所有的点连起来就能描绘出当前的超声探头辐射区内所有的高度和幅值的二维曲线图，而在曲线的每一个波峰位置，就是对应的各种高度信息如图2。理论上单个超声波（换能器）探头就能测量到所有这些信息。但实际的应用中，我们发现随机摆放杯子，总能找到某些特殊的位置，杯高或者其他高度的漫反射信号强度会变得非常弱，以至于当成一些干扰信号忽略掉，导致换能器探头无法检测到有杯子的存在，也即存在漏检的可能性，例如在设置有3个探头时，3个探头会在同一时刻接收到的独立的3组曲线图，如果此时只有探头1的话，那***是检测不到有杯子的，但在探头2和探头3的位置能探测到该杯子的信号，以至于如果只有1个探头时就会发生漏检的问题。或者，只有探头2的位置有杯子的信息，而探头1和探头3都检测不到杯子信号。所以探头的个数的多少决定其发生漏检的概率。如果只有一个探头时发生漏检的概率在10%左右，主要原因是因为杯子高度的表面并非理想的平面，会有一定的角度，当摆放的角度刚好把漫反射的信号落在探头无法检测的区域外，那探头就无法接收到该杯子高度信息，使得杯子的检测会存在误差，无法准确检测到杯子的存在而使饮水机的自动控制使用受到限制。The ultrasonic measurement technology is very cost-effective in the realization of the automatic water supply and water stop of the water dispenser. The ultrasonic wave is to use the characteristics of the reflection of the sound wave encountering obstacles. The ultrasonic (transducer) probe emits the sound wave, and then receives the diffuse reflection from all directions, and then obtains a curve f (x, y) with two-dimensional characteristics as shown in Figure 1 . The X-axis is time, corresponding to the information of various heights of the area radiated by the sound wave, and the Y-axis is the amplitude, corresponding to the information of the reflection intensity at the height of the X-axis. In the entire ultrasonic radiation range of the water outlet of the water dispenser, there will be a lot of height and amplitude information f1(x1, y1), f2(x2, y2)..., fn(xn, yn), all the points are connected The two-dimensional curve graph of all the heights and amplitudes in the radiation area of the current ultrasonic probe can be depicted, and at each peak position of the curve, the corresponding height information is shown in Figure 2. In theory a single ultrasonic (transducer) probe can measure all of this information. However, in practical applications, we found that by placing the cups randomly, some special positions can always be found. The intensity of the diffuse reflection signal at the height of the cup or other heights will become so weak that it is ignored as some interference signals, resulting in energy conversion. The detector probe cannot detect the existence of the cup, that is, there is the possibility of missing detection. For example, when there are 3 probes, the 3 probes will receive 3 independent sets of graphs at the same time. If only the probe is present at this time. If it is 1, the system cannot detect the cup, but the signal of the cup can be detected at the positions of probe 2 and probe 3, so that if there is only one probe, there will be a problem of missed detection. Or, only the position of probe 2 has the cup information, and neither probe 1 nor probe 3 can detect the cup signal. Therefore, the number of probes determines the probability of missed detection. If there is only one probe, the probability of missed detection is about 10%. The main reason is that the surface of the cup height is not an ideal plane, and there will be a certain angle. When the angle is placed, the diffuse reflection signal falls on the probe and cannot be detected. Outside the area, the probe cannot receive the height information of the cup, so that there will be errors in the detection of the cup, and the existence of the cup cannot be accurately detected, which limits the use of automatic control of the water dispenser.

为了解决上述问题，参照图1至图15，在本申请一实施例中，该饮水机的控制方法包括：In order to solve the above problems, referring to FIG. 1 to FIG. 15 , in an embodiment of the present application, the control method of the water dispenser includes:

步骤S100、按照预设的顺序或随机控制N个超声波探头工作；Step S100, control the N ultrasonic probes to work according to a preset order or randomly;

本实施例中，在控制N个超声波探头工作前，可以先将N个超声波探头进行排序，例如进行1、2、3、……、N的排序，在饮水机工作时，按照预设的顺序的控制，可以是按照序号从小到大的控制，或者按照序号从大到小的控制，或者先控制奇数号的超声波探头工作，再控制偶数号的超声波探头工作等，或者随机控制N个超声波探头工作。在实际应用时，可以根据客户的需求，设置定制的顺序，规划出一个循环的列表顺序，并按定制的顺序切换。具体地，在按照序号从小到大的顺序控制N个超声波探头发出超声波信号时，在N个超声波探头中，任意个超声波探头发出超声波信号，其余的N-1个超声波探头则接受该超声波探头发出的超声波信号，例如No.1超声波探头发出超声波信号，No.2~No.N超声波探头则接收No.1超声波探头发出的超声波信号。以此类推，直至No.N超声波探头发出超声波信号，而No.1~No.N-1则接收No.N超声波探头发出超声波信号。在按照序号从大到小的顺序控制N个超声波探头发出超声波信号时，在N个超声波探头中，则是No.N超声波探头发出超声波信号，而No.1~No.N接收No.N超声波探头发出超声波信号。以此类推，No.1超声波探头发出超声波信号时，No.2~No.N超声波探头则接收No.1超声波探头发出的超声波信号，从而完成对N个超声波探头的控制。对探头的不同控制方法，会对饮水机的出水时间有影响，本实施例可以结合到产品的应用场景要求进行设置，此处不做限制。如图15所示，No.N超声波探头发出超声波信号，No.1~No.N-1则接收No.N超声波探头发出超声波信号产生漫反射之后的回拨信息。In this embodiment, before controlling the N ultrasonic probes to work, the N ultrasonic probes can be sorted first, for example, 1, 2, 3, . . . The control can be controlled according to the serial number from small to large, or according to the serial number from large to small, or first control the operation of the odd-numbered ultrasonic probes, and then control the even-numbered ultrasonic probes, etc., or randomly control N ultrasonic probes Work. In practical application, you can set the order of customization according to the needs of customers, plan a circular list order, and switch according to the order of customization. Specifically, when the N ultrasonic probes are controlled to send out ultrasonic signals according to the sequence number from small to large, among the N ultrasonic probes, any ultrasonic probe sends out ultrasonic signals, and the remaining N-1 ultrasonic probes receive the ultrasonic signal sent by the ultrasonic probe. For example, No.1 ultrasonic probe sends out ultrasonic signals, and No.2~No.N ultrasonic probes receive ultrasonic signals from No.1 ultrasonic probe. And so on, until No.N ultrasonic probe sends out ultrasonic signal, and No.1~No.N-1 receive ultrasonic signal from No.N ultrasonic probe. When the N ultrasonic probes are controlled to send out ultrasonic signals according to the sequence number from large to small, among the N ultrasonic probes, No.N ultrasonic probes send out ultrasonic signals, and No.1~No.N receive No.N ultrasonic waves The probe emits an ultrasonic signal. By analogy, when No.1 ultrasonic probe sends out ultrasonic signals, No.2~No.N ultrasonic probes receive ultrasonic signals from No.1 ultrasonic probe, so as to complete the control of N ultrasonic probes. Different control methods for the probe will affect the water discharge time of the water dispenser. This embodiment can be set in combination with the requirements of the application scenario of the product, which is not limited here. As shown in Figure 15, the No.N ultrasonic probe sends out ultrasonic signals, and No.1~No.N-1 receive the callback information after the ultrasonic signal sent by the No.N ultrasonic probe produces diffuse reflection.

步骤S200、获取N个所述超声波探头检测的回波信号；Step S200, acquiring N echo signals detected by the ultrasonic probe;

本实施例中，在控制N个所述超声波探头中任意一个超声波探头发出超声波信号时，其余N-1个超声波探头则会接收该超声波探头发出的超声波信号，并且按照预设顺序对N个所述超声波探头完成控制后，N个超声波探头均会至少一次地作为接收探头接收到其他超声波探头的发出的超声波信号，例如该超声波信号在遇到饮水机的接水座、饮水机主体、或者放置在接水座上的盛水容器而反射回去而被各个对应位置的所述超声波探头所接收时，则可以在N个超声波探头中任意一个作为发射探头发出的信号被遮挡物遮挡时，被其他作为接收探头接收到反射回来的回波信号。In this embodiment, when any one of the N ultrasonic probes is controlled to send out an ultrasonic signal, the remaining N-1 ultrasonic probes will receive the ultrasonic signal sent by the ultrasonic probe, and the N all ultrasonic probes will be sent in a preset order. After the above-mentioned ultrasonic probes are controlled, each of the N ultrasonic probes will serve as receiving probes to receive ultrasonic signals from other ultrasonic probes at least once. When the water container on the water receiving seat is reflected back and received by the ultrasonic probes at each corresponding position, when the signal sent by any one of the N ultrasonic probes as the transmitting probe is blocked by the blocker, it can be blocked by other ultrasonic probes. As a receiving probe, it receives the reflected echo signal.

步骤S300、根据N个所述超声波探头检测的回波信号确定放置于所述饮水机盛水位置的盛水容器的盛水容量；Step S300, determining the water holding capacity of the water holding container placed at the water holding position of the water dispenser according to the echo signals detected by the N ultrasonic probes;

本实施例中，可以理解的是，在超声波探头发出去的超声波信号遇到接水座、饮水机主体等固有距离而反射回的回波信号，这些回波信号因为接水座、饮水机主体的固有而可以理解为固有回波信号，以及超声波信号遇到不同物理尺寸的盛水容器反射回的回波信号是变化回波信号，以及在接水的过程中，盛水容器中随着水的高度不断变化，接收到的回波信号也是变化回波信号。当作为接收探头的超声波探头与物体的距离不同时，则超声波探头接收到的反射信号的信号强度不同，物体距离超声波探头越远，则接收的反射的信号强度越小；而物体距离超声波探头越近，则接收的反射的信号强度越大。通过实验发现信号强度和距离之间为线性关系，因此根据反射信号的强度即可简单的计算出盛水容器与各个发射探头距离。当盛水容器放置于接水座时，超声波探头从盛水容器上方向放置盛水容器的接水座等固有角度发送超声波信号，则可以检测盛水容器顶部、杯壁、及杯壁等距离参考原点的距离，如果盛水容器所在平面距离参考原点的距离已知或可以通过检测得到，则通过再未放置盛水容器时检测到的固有回波信号，以及放置盛水容器时检测到的变化回波信号之间的差值或者变化规律，即可确定接水座是否放置有盛水容器、盛水容器的盛水容量，以及盛水容器中随盛水时间变化的动态盛水过程。In this embodiment, it can be understood that when the ultrasonic signal sent by the ultrasonic probe encounters the inherent distance of the water socket and the water dispenser body, the echo signals are reflected back. These echo signals are caused by the water socket and the water dispenser body It can be understood as an inherent echo signal, and the echo signal reflected back by the ultrasonic signal encountering water containers of different physical sizes is a variable echo signal, and in the process of receiving water, the water in the water container will follow the water in the water container. The height is constantly changing, and the received echo signal is also a changing echo signal. When the distance between the ultrasonic probe as the receiving probe and the object is different, the signal intensity of the reflected signal received by the ultrasonic probe is different. The farther the object is from the ultrasonic probe, the smaller the reflected signal intensity is; The closer the signal is, the stronger the received reflected signal will be. Through experiments, it is found that there is a linear relationship between the signal intensity and the distance, so the distance between the water container and each transmitting probe can be simply calculated according to the intensity of the reflected signal. When the water container is placed on the water receiving seat, the ultrasonic probe sends ultrasonic signals from the inherent angle such as the water receiving seat where the water container is placed above the water container, and the distance between the top of the water container, the cup wall, and the cup wall can be detected. The distance from the reference origin, if the distance between the plane where the water container is located and the reference origin is known or can be obtained by detection, then the inherent echo signal detected when no water container is placed, and the detected echo signal when the water container is placed is used. By changing the difference or changing law of the echo signals, it can be determined whether a water container is placed on the water receiving seat, the water holding capacity of the water container, and the dynamic water filling process in the water container that changes with the water filling time.

本实施例中，在根据N个所述超声波探头检测的回波信号确定接水座有盛水容器放置，且确定放置于所述饮水机盛水位置的盛水容器的盛水容量时，则可以根据盛水容量控制饮水机工作，以进行出水。在实际应用时，可以根据计算的盛水容器的高度、形状、截面积等确定盛水容器的盛水容量，进而根据盛水容器的高度、形状、截面积，确定饮水机的出水方式。具体而言，根据盛水容器的高度、形状、截面积的不同，饮水机的出水方式也可以设置为不同，例如对于高度较高，不易溅落的盛水容器，在初始出水时可以以较快的出水速度和出水量进行出水，随着盛水容器的水量增加，而逐渐减小出水速度。而对于高度较低的容器，则可以以较慢的出水速度或者出水量进行出水。同理，根据盛水容器截面积的不同，盛水容器是方形、圆形还是不规则等形状的不同，以较为合理的出水速度、出水量进行出水。此外，出水的停止时间也可以根据盛水容器的盛水容量来确定饮水机的出水总量，而进行确认，或者根据N个所述超声波探头实时检测的回波信号，进行动态控制。并且，在获知盛水容器的盛水容量来控制饮水机的出水量的同时，还可以根据安全值、饮水机的出水温度等因素考虑，或者根据用户的饮水习惯、或者根据大数据分析常规的接水习惯等确定饮水机的出水量，例如饮水机的出水量可以设置为盛水容器容量的70~90%。或者，通过设置盛水完毕后盛水容器中的最终液位(即目标液位)与盛水容器的容器高度之比来确定饮水机的出水量。例如，当用户预设的盛水高度比例值为70％时，盛水完毕后的盛水容器中的最终液位为盛水容器的容器高度的70％。通过控制饮水机的出数量，可以根据盛水容器不同，保证盛水完毕后盛水容器中的最终液位满足用户的需求，且不会出现出水不够或溢水的情况。In this embodiment, when it is determined that a water container is placed in the water receiving seat according to the echo signals detected by the N ultrasonic probes, and the water container capacity of the water container placed at the water container position of the water dispenser is determined, then The work of the water dispenser can be controlled according to the water holding capacity to discharge water. In practical application, the water holding capacity of the water container can be determined according to the calculated height, shape, cross-sectional area, etc. of the water container, and then the water outlet method of the water dispenser can be determined according to the height, shape, and cross-sectional area of the water container. Specifically, according to the height, shape and cross-sectional area of the water container, the water outlet method of the water dispenser can also be set to be different. The water outlet speed and water output volume are adjusted according to the water outlet speed, and the water outlet speed gradually decreases as the water volume of the water container increases. For containers with a lower height, water can be discharged at a slower water output speed or water output. In the same way, according to the different cross-sectional area of the water container, whether the water container is square, round or irregular, the water is discharged at a more reasonable water output speed and water output. In addition, the stop time of water discharge can also be confirmed according to the water holding capacity of the water container to determine the total water output of the water dispenser, or be dynamically controlled according to the echo signals detected in real time by the N ultrasonic probes. In addition, while knowing the water capacity of the water container to control the water output of the water dispenser, it can also be considered according to factors such as safety value, water temperature of the water dispenser, or according to the user's drinking habits, or according to big data analysis of conventional methods. The water output of the water dispenser is determined by the habit of receiving water. For example, the water output of the water dispenser can be set to 70~90% of the capacity of the water container. Alternatively, the water output of the water dispenser is determined by setting the ratio of the final liquid level (ie, the target liquid level) in the water container after the water is filled to the height of the water container. For example, when the user preset ratio of the water holding height is 70%, the final liquid level in the water holding container after the water holding is completed is 70% of the container height of the water holding container. By controlling the output quantity of the water dispenser, it can be ensured that the final liquid level in the water container can meet the needs of the user after filling the water according to the different water containers, and there will be no shortage of water or overflow.

本申请通过按照预设的顺序控制N个超声波探头工作；以根据获取N个所述超声波探头检测的回波信号；从而根据N个所述超声波探头检测的回波信号确定放置于所述饮水机盛水位置的盛水容器的盛水容量；进而根据确定的所述盛水容器的盛水容量控制所述饮水机的出水量。本申请能够根据N个超声波探头检测回波信号，获取盛水容器的盛水容量以得到饮水机的控制策略，可以提高自动出水的检测精度，可以扩大检测范围，减少检测盲区，降低盛水容器误检或者漏检的概率。本申请可以在每次采用的盛水容器不同，也能够对盛水容器进行准确检测，以实现准确定的根据盛水容器实现自动、智能化出水。The present application controls the operation of N ultrasonic probes according to a preset sequence; obtains echo signals detected by the N ultrasonic probes; thus determines the location of the water dispenser according to the echo signals detected by the N ultrasonic probes The water holding capacity of the water holding container at the water holding position; and then the water output of the water dispenser is controlled according to the determined water holding capacity of the water holding container.

可以理解的是，根据饮水机的使用环境不同，盛水容器的物理尺寸会存在更换与不更换的情况，而盛水容器的不同，则会改变饮水机的出水量及饮水机的响应速度和出水速度。例如在医院、商场、酒店等公共场所，盛水容器可能为相同的一次性水杯，因此盛水容器大多数情况下不会更换。而在企业、家庭等盛水容器可能根据用户的不同而出现不同时，例如盛水容器可能为保温杯、玻璃杯、陶瓷杯，这些盛水容器的形状、高度、体积、截面积均不同，并且杯壁的外沿也会根据是否带有杯盖而出现，甚至根据杯盖的不同也会存在不同，例如杯子是否带螺纹，是否为光面等，因此根据盛水容器的不同所带来的影响，需要在饮水机工作前，获取当下的盛水容器的物理尺寸，并综合考虑预设盛水参数和物理尺寸而确定出最终的目标盛水量，保证饮水机在以该目标盛水参数出水后，能够在当下的盛水容器中获得预期的液位高度及容量，实现全自动和智能化盛水。It is understandable that, depending on the use environment of the water dispenser, the physical size of the water container may or may not be replaced, and the difference in the water container will change the water output of the water dispenser and the response speed of the water dispenser. water outlet speed. For example, in public places such as hospitals, shopping malls, hotels, etc., the water container may be the same disposable water cup, so the water container will not be replaced in most cases. However, when the water containers such as enterprises and families may appear different according to different users, for example, the water containers may be thermos cups, glass cups, and ceramic cups. The shape, height, volume and cross-sectional area of these water containers are different. And the outer edge of the cup wall will also appear according to whether there is a cup cover, and even different according to the cup cover, such as whether the cup is threaded, whether it is smooth, etc., so it depends on the difference of the water container. It is necessary to obtain the physical size of the current water container before the water dispenser works, and comprehensively consider the preset water parameters and physical dimensions to determine the final target water volume, to ensure that the water dispenser uses the target water parameters. After the water is discharged, the expected liquid level and capacity can be obtained in the current water container, realizing automatic and intelligent water filling.

本实施例中，根据盛水容器的物理尺寸是否变化，N个所述超声波探头工作状况也可以设置为不同。In this embodiment, according to whether the physical size of the water container changes, the working conditions of the N ultrasonic probes can also be set to be different.

本实施例中，在按照预设的顺序控制N个所述超声波探头工作时，也即每一个超声波探头作为发射探头时，当前发射探头不变，其余的N-1个超声波探头作为接收探头，连续对发射探头发出的超声波采集n次，共采集到n*N条曲线。然后控制切换下一个超声波探头作为发射探头，也是连续采集n次，最后所有超声波探头都循环一遍，得到n*N*N条曲线。本实施例通过同一个发射探头连续采集，得到的n次的曲线数据比较平滑，适合测普通的不带螺纹口（保温杯）的杯子，以及适用于盛水容器的物理尺寸会不常更换的情况，通过多次采集数据，有利于提高盛水容器的位置、尺寸等的检测准确性，从而提高饮水机的出水准确率。In this embodiment, when the N ultrasonic probes are controlled to work according to the preset order, that is, when each ultrasonic probe is used as a transmitting probe, the current transmitting probe remains unchanged, and the remaining N-1 ultrasonic probes are used as receiving probes. The ultrasonic waves emitted by the transmitting probe are continuously collected n times, and a total of n*N curves are collected. Then control to switch the next ultrasonic probe as the transmitting probe, which is also continuously collected n times, and finally all ultrasonic probes are cycled again to obtain n*N*N curves. This embodiment uses the same transmitting probe to continuously collect, and the obtained n-th curve data is relatively smooth, which is suitable for measuring ordinary cups without a threaded mouth (insulation cup), as well as for water containers whose physical dimensions will not be changed frequently. In this case, by collecting data multiple times, it is beneficial to improve the detection accuracy of the position and size of the water container, thereby improving the water output accuracy of the water dispenser.

参照图3，在一实施例中，在不确定当前作为发射探头的超声波探头情况下，各个作为接收探头的超声波探头仅采集一次数据，然后进行发射探头切换，也即所述按照预设的顺序或随机控制N个所述超声波探头工作的步骤包括：Referring to FIG. 3 , in one embodiment, when the current ultrasonic probe serving as the transmitting probe is uncertain, each ultrasonic probe serving as the receiving probe collects data only once, and then switches the transmitting probe, that is, according to the preset order. Or the steps of randomly controlling the N ultrasonic probes to work include:

步骤S121、按照预设的顺序或随机控制N个所述超声波探头中的每一个超声波探头工作为发射探头，并在工作为发射探头时发出超声波信号；以及，Step S121, controlling each ultrasonic probe in the N ultrasonic probes to work as a transmitting probe according to a preset order or randomly, and sending out ultrasonic signals when working as a transmitting probe; and,

本实施例中，当前发射探头只采一次，得到N条曲线，然后切换N次探头又得到N条曲线，最后一个循环就得到N*N调曲线，当然在其他实施例中，在不考虑响应特性的情况下，增加一个循环次数n，也可以得到N*N*n条曲线，以提高饮水机的出水准确率。本实施例可以实现在较短的时间内切换完所有位置的发射探头，动态响应比较好，但数据的波动比较大，适合测量带螺纹的杯子，以及适用于盛水容器的物理尺寸会存在更换的情况，通过N个超声波探头快速对各个角度进行超声波信号的发射并接收回波信号，有利于对经常更换的盛水容器进行检测，从而精准的检测盛水容器是否放置于接水座，有利于提高饮水机的响应速度。In this embodiment, the current transmitting probe is only collected once to obtain N curves, and then N curves are obtained by switching the probe N times, and N*N tuning curves are obtained in the last cycle. Of course, in other embodiments, the response is not considered. In the case of the characteristic, adding a cycle number n can also obtain N*N*n curves to improve the water output accuracy of the water dispenser.

参照图4，在一实施例中，所述根据所述回波信号确定放置于所述饮水机的出水口对应位置的盛水容器的盛水容量的步骤包括：4, in one embodiment, the step of determining the water holding capacity of the water container placed at the position corresponding to the water outlet of the water dispenser according to the echo signal includes:

步骤S410、根据所述回波信号形成的曲线，对所述曲线进行区间划分，以获得曲线的有效区间；Step S410, according to the curve formed by the echo signal, perform interval division on the curve to obtain the effective interval of the curve;

步骤S430、根据每一所述曲线的波峰值获得所述盛水容器的物理尺寸，以根据所述物理尺寸计算获得所述盛水容器的盛水容量。Step S430: Obtain the physical size of the water container according to the peak value of each curve, so as to calculate and obtain the water container capacity of the water container according to the physical size.

参照图13及图14，本实施例中，在控制N个所述超声波探头中任意一个作为发射探头发出的信号被遮挡物遮挡时，被其他作为接收探头接收到反射回来的回波信号，根据接收到的回波信号，即可获得采集的所有曲线F1…n(x1…xn，y1…yn)。根据获得曲线来计算出每一条曲线的所有波峰信息p1-n(x1…xn，y1…yn)。然后对所有的波峰信息进行处理。Referring to FIGS. 13 and 14, in this embodiment, when the signal sent by any one of the N ultrasonic probes as a transmitting probe is controlled to be blocked by an obstruction, the echo signals that are reflected back by other receiving probes are received, according to From the received echo signals, all the collected curves F1...n (x1...xn, y1...yn) can be obtained. According to the obtained curves, all the peak information p1-n (x1...xn, y1...yn) of each curve are calculated. Then all the peak information is processed.

具体而言，所述根据所述的回波信号形成的曲线，对所述曲线进行区间划分，以获得曲线的有效信息区间的步骤包括：Specifically, the step of dividing the curve according to the curve formed by the echo signal to obtain the effective information interval of the curve includes:

确定曲线的盲区区间；Determine the blind zone interval of the curve;

本实施例中，将各个曲线进行区间划分，从而获得各个曲线的区间段，根据各个区间段来获得有效信息区间。In this embodiment, each curve is divided into intervals, so as to obtain interval segments of each curve, and valid information intervals are obtained according to each interval segment.

其中，波峰的阈值：由于超声波探头采集的是模拟信号，因此每条曲线都会存在一定的干扰噪声，为了避免误触发，本实施例通过设置一个波峰阈值，将超过波峰阈值的区间设置为有效区间，而将低于波峰阈值的部分进行剔除，以避免干扰信号对波峰的信号提取。曲线的盲区区间A：所述曲线的盲区区间为各所述超声波探头获取的自身发出的超声波信号范围，该区间探头的盲区信息，这部分的数据是超声波探头作为发射探头发射的超声波信号直接被其他作为接收探头接收到的回波信号，例如超声波信号经过机壳介质传导过来的信号，属于干扰或者无用的信息。曲线的有效信息区间B：该区间的数据包括杯高、液高、杯体形状、体积等信息。曲线的无效信息区间C：所述曲线的无效信息区间为各所述超声波探头获取的饮水机供盛水容器放置的接水座的回波信号范围，属于放水杯的接水座的位置信息，例如接水座的高度，以及供超声波探头的设置接水台位置，也可以去除。Among them, the threshold of the wave peak: because the ultrasonic probe collects the analog signal, there will be a certain amount of interference noise in each curve. In order to avoid false triggering, in this embodiment, a wave peak threshold is set, and the interval exceeding the wave peak threshold is set as the valid interval , and the part below the peak threshold is eliminated to avoid interfering with the signal extraction of the peak. Blind zone interval A of the curve: The blind zone interval of the curve is the ultrasonic signal range obtained by each ultrasonic probe, and the blind zone information of the probe in this interval, this part of the data is the ultrasonic signal transmitted by the ultrasonic probe as the transmitting probe. Other echo signals received as receiving probes, such as ultrasonic signals transmitted through the casing medium, are interference or useless information. Effective information interval B of the curve: The data in this interval includes information such as cup height, liquid height, cup body shape, and volume. Invalid information interval C of the curve: the invalid information interval of the curve is the echo signal range of the water receiving seat of the water dispenser for the water container obtained by each ultrasonic probe, which belongs to the position information of the water receiving seat of the water cup, For example, the height of the water receiving seat and the position of the water receiving table for the ultrasonic probe can also be removed.

参照图5、在一实施例中，根据每一所述曲线的波峰值获得所述盛水容器的物理尺寸的步骤包括：5 , in one embodiment, the step of obtaining the physical size of the water container according to the peak value of each curve includes:

本实施例中，由于各个超声波探头设置的位置不同，以及盛水容器放置的位置不同，在超声波探头与盛水容器之间进行超声波信号的反射时，反射回超声波探头的信号会发生变化，并且会存在较优的回波信号，因此需要从获取的所有波峰信号中，选取较优波峰值，来确定的物理尺寸。具体地，可以将所有的曲线（n*N*N）B区间的波峰数据都提取出来，排成一个队列p1-pn。然后把每一个波峰数据的pn(xn，yn)以p（x）为波峰参考档位，以一定的差值（例如正负Δx）对数据进行归整，选出个数最多的那组数据px(x，y)定为物理尺寸。In this embodiment, due to the different placement of the ultrasonic probes and the placement of the water container, when the ultrasonic signal is reflected between the ultrasonic probe and the water container, the signal reflected back to the ultrasonic probe will change, and There will be a better echo signal, so it is necessary to select a better peak value from all the acquired peak signals to determine the physical size. Specifically, all the peak data in the interval B of the curve (n*N*N) can be extracted and arranged into a queue p1-pn. Then take the pn(xn, yn) of each peak data with p(x) as the peak reference gear, normalize the data with a certain difference (such as positive and negative Δx), and select the group of data with the largest number px(x,y) is the physical size.
